It's still a work-in-progress, but I've been working on the gr-qtgui 
stuff that adds QT-based GUI capabilities. One thing I've added recently 
is a qt-based version of the benchmark_rx digital code. When you run it 
with the -G option, it will show you two plots; one of the received 
signal, and the other is of the output of the mpsk_receiver. If you 
click on the Constellation tab, you will see the symbol mapping.

There is also a version of benchmark_loopback with a Qt interface that 
will also show you this.
